Usage

Converting a raster to a TIN will not, in and of itself, produce a better surface. You need ancillary data that's compatible with, and improves, the surface definition. Such data could be added to the TIN using the Edit TIN tool.

The default maximum allowable difference between the height of the input raster and the height of the output TIN is 1/10 of the z range of the input raster.

While the maximum size of a TIN that can be used under Win32 is between 15 to 20 million nodes, it's recommended to cap the size at a few million. Large input rasters, and small z-tolerance settings, may exceed this. If size is an issue, consider processing subsets.
